dtencwed December $0, 1912. iierial Filo. iidt'fi'iil To all whom it mayconcern;

Be it known that I, MICHAEL E. RYAN, a citizen of the United States,residing in the city of Bridgeport, county of Fairfield, State -ofConnecticut, have invented certain new nents in wire chain links, andhas for its object to form a link from-metal so that it will besubstantially endless, and at the same time to greatly strengthen thelink, and with these e'nds,in view my invention consists in certainmethods and details of construction hereinafter fully set forth and thenparticularly pointed out in the claims Wlil0l1l60l1- elude thisdescription.

In the accompanying drawing Figure -1 is an elevation showing a blankwith eyes formed at the ends thereof in accordance with my improvementlig. 2 is a plan view of a completed link preparatory to the weldingoperation l ig. 3 aside elevation of such link-Figs. 1 and 5 are plsnviews re spectively of obverse and reverse faces of a completely weldedlink, and Fig.6 an enlarged section at the line a}, w, of Fig. 5.

' Similar numerals of reference denote like parts in the several figuresof the drawing;

In carrying out my improvement 1 form eyes 1, 2, at the ends of asuitable wire blank 3 by bending the ends in the arc of a circle and in'rever e directions. The blank is then bent at its niddle portion so asto form a bow i and to bring the eyes together so that they will be in aplane at right angles to the plane of the how The eyes are then pressedtogether and welded from the point where one eye joins one side wire 5of the bow to the point Where the other eye joins the other side wire 6of said how, this welding being preferably efiected without joining theends of the Wire to the body of the wire, the weld being denoted b thenumeral 7, This will form a link in w .ich the eyes are welded to:gether from the base portion of the eye 1 where it joins integrally theside wire 6 around throughout the circuit of the eyes to the baseportion of the eye where it joins integrally the side wire 5, so thatthe link will be formed from one snbstentially endless: piece of wirethe eye ofthe link being of double thickness.

A link made as above described is not only exceedingly strong butinsures the saving of considerable wire'which would otherwise beutilized in anchoring the ends of the eyes to the side wires.

In welding together metal parts great trouble is generally experiencedwith the bur that is incident to the welding, and the Welded articleshave to undergo a special treatment such as tumbling in order to removethis bar. lfn my improvement any undue flow of metal is'distributed andtaken care of within the space between the outer and inner peripheriesof the eyes as is clearly shown at Fig. 6 and it is impossible for anyprojecting bur to form and therefore no tumbling or other finishingoperation is necessar a It is not necessary, in forming the eyes, to

abut the ends ol the e es a 'ainst the bod of the wire, since said endsmay be slightly spaced from the wire, itfhein I clear that in bothinstances after welding t e link will he practically termed from anendless wire of Pittman-loll Agni". Ml, il'tlllsl,

double thickness at the eye portion, and in this connection I would saythat any joining of these ends to the body oi" the wire by the operationof welding would be merely incidental.

I do not wish to be understood as claiming the welding of the e eportions of the link together such as con d be effected in the instanceor eyes which were formed by bend-., ing the'ends of the blank in thesome direc tion since this would not ailord sin endless circuit of thewire, neither do I wish to lie understood as claimingihe manner in whichthe link itself is formed irrespective oi lweld- 1 in But; r What I doclaim as new anddesire to sc- 'cure by Letters Patent isr y chei'n' linkcomprising a how portion end two eyes disposed sideby the metal gether.
